8 Artists Who Poured Their Heart and Soul Into Their Work (Also: Their Blood and Urine) All artists put a little bit of their soul into every piece. But these artists put their soul – and a whole lot more – into their art. 1. Hair and Nails When Hananuma Masakichi learned he was dying of tuberculosis, he wanted to give his girlfriend a way to remember him. During the construction, Masakichi even sacrificed pieces of his own body to help his wooden doppelganger come to life. Masakichi finished his statue in 1885 and put it on display. When Robert Ripley began collecting the world's oddities in the 1930s, Masakichi's statue was one of the first items he acquired, paying a San Francisco saloon-owner $10 for it. 2. Van Gogh painted some famous self-portraits. The first Self was purchased by one of the Britart movement's biggest early supporters, Charles Saatchi, who paid £13,000 for it. 3. All artists suffer for their art, but Lani Beloso has made her suffering into art instead. 4. Few pieces of art have evoked emotions like Andres Serrano's 1987 Immersion (Piss Christ) . 5.

"Chrysler Air Raid Siren" What you see pictured above is a Chrysler Air Raid Siren, the most powerful siren in the world. It's the size of a car, measuring near 12-feet in length and standing more than 6-feet tall. It also weighs twice as much as today's typical car. This gigantic siren is powered by an 180-HP Chrysler Industrial V-8 HEMI® gasoline engine. The super-duty engine directly drives a three-stage compressor that blows 2,610 cubic feet of air a minute, at nearly 7 PSI, into a giant siren rotor. The compressed air screams through the chopper and out through six giant horns with an exit velocity of 400 miles per hour. Chrysler Air Raid Siren - Specifications At maximum RPM, with short acoustic-coupler (horn-extension) the Bell-Chrysler air-raid siren generates 138 dbC (approximately 134 dbA) at 100 ft. or 30 meters, 0 degrees on axis, in anechoic, full space environment, and an estimated 30,000 watts of overall acoustic power. How loud is 138 dB? Siren coverage is based on a 10 dB loss factor.

New Car Engine Sends Shock Waves Through Auto Industry Despite shifting into higher gear within the consumer's green conscience, hybrid vehicles are still tethered to the gas pump via a fuel-thirsty 100-year-old invention: the internal combustion engine. However, researchers at Michigan State University have built a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids. Their so-called Wave Disk Generator could greatly improve the efficiency of gas-electric hybrid automobiles and potentially decrease auto emissions up to 90 percent when compared with conventional combustion engines. The engine has a rotor that's equipped with wave-like channels that trap and mix oxygen and fuel as the rotor spins. The Wave Disk Generator uses 60 percent of its fuel for propulsion; standard car engines use just 15 percent. Researchers estimate the new model could shave almost 1,000 pounds off a car's weight currently taken up by conventional engine systems.

Brain Scans of Rappers Shed Light on Creativity Rappers making up rhymes on the fly while in a brain scanner have provided an insight into the creative process. Freestyle rapping — in which a performer improvises a song by stringing together unrehearsed lyrics — is a highly prized skill in hip hop. But instead of watching a performance in a club, Siyuan Liu and Allen Braun, neuroscientists at the US National Institute on Deafness and Other Communication Disorders in Bethesda, Maryland, and their colleagues had 12 rappers freestyle in a functional magnetic resonance imaging (fMRI) machine. The artists also recited a set of memorized lyrics chosen by the researchers. The results parallel previous imaging studies in which Braun and Charles Limb, a doctor and musician at Johns Hopkins University in Baltimore, Maryland, looked at fMRI scans from jazz musicians. “We try to stick with more natural creative processing, and when we do that we see this decrease in the dorsal lateral regions,” says Braun.

Image evolution What is this? A simulated annealing like optimization algorithm, a reimplementation of Roger Alsing's excellent idea. The goal is to get an image represented as a collection of overlapping polygons of various colors and transparencies. We start from random 50 polygons that are invisible. Fitness is a sum of pixel-by-pixel differences from the original image. This implementation is based on Roger Alsing's description, though not on his code. How does it look after some time? 50 polygons (4-vertex) ~15 minutes 644 benefitial mutations 6,120 candidates 88.74% fitness 50 polygons (6-vertex) ~15 minutes 646 benefitial mutations 6,024 candidates 89.04% fitness 50 polygons (10-vertex) ~15 minutes 645 benefitial mutations 5,367 candidates 87.01% fitness 50 polygons (6-vertex) ~45 minutes 1,476 benefitial mutations 23,694 candidates 93.35% fitness 50 polygons (6-vertex) ~60 minutes 1,595 benefitial mutations 28,888 candidates 93.46% fitness Does it work on all images? It depends, success varies.

The 5 Most Terrifying Civilizations In The History of the World They say that those who ignore history are doomed to repeat it, so pay attention for Christ's sake. It turns out that many of our ancestors achieved levels of violence that take them right out of the realm of "badass" and into the less cool area of ball-shriveling atrocity. These are the civilizations you don't want to face during, say, your next time travel adventure. History is kind of spotty on the Celts (they never wrote anything down, and many of the witnesses died brutally) but what facts survived confirm one thing: They had gigantic Celtic balls. First of all, they had a thing for severed heads. If they felt that yours was a head of particular importance, they'd embalm it and whip it out at parties to brag about how awesome they were. The reason for all of these head-chopping-good-times was that the Celts believed that the head held the soul, and so if you cut a dead guy's head off before all of that juicy soul leaked out of it, it was yours. A modern Celt. Yes. It was iron.

How to Build a Solar Heating Panel with Soda Cans If you’ve got good sun exposure on one side of your house, you can take advantage of free heat from the sun with this DIY solar heating panel, which uses old soda cans to collect and transfer the sun’s energy into your house. Sometimes, low-tech solar devices are much better than high-tech ones for home use, as they not only tend to be cheaper to make, but will also last much longer before any repairs or maintenance are necessary. And even better, they can be built in part from repurposed or recycled components, which is something you don’t see very often in new solar devices. This solar space heater design uses old soda cans to increase the surface area for heat transfer inside of it, and in its most basic design, uses no external power to move the air. Double-glazed glass or polycarbonate panels make up the front of the device, allowing the sun’s rays to enter it while restricting heat loss to the outside air, and the box is also insulated for more efficiency.

Listen: The Music of a Human Brain | Wired Science Musical score based on the neurological activity of a 31-year-old woman. Image: Lu et al./PLoS One Researchers have turned human mental activity into music, and it sounds uncannily like free-form jazz piano. The new brain-to-sound method translates a brain’s electrical fluctuations to pitch and blood flows to intensity. “We hope the on-going progresses of the brain signals-based music will properly unravel part of the truth in the brain,” wrote neuroscientists led by Jing Lu and Dezhong Yao of China’s University of Electronic Science and Technology in a study Nov. 14 in the online journal PLoS One. In earlier work, the researchers based their translation solely on scalp-conducted electrical activity, familiar to most people through electroencephalograph (EEG) readings, but the resulting notation didn’t quite rise to the level of music. In the new study, they added blood flow measurements from an fMRI machine to the mix. “Music therapy would be a good application of brain music,” said Lu.

Ausweis Ausweis A Reality-Hacking Experiment. The world's changing. We're getting so concerned with the descriptions and symbols that represent ideas, we're losing all contact with the substance. On a tape I bought at a yard sale, I heard the narrator say, "People are conditioned to believe the printed word." You know I really thought that people would laugh and not let me get anywhere with them. But success came really quickly. My next big success came with the "50 Cents Off" card. What was it that compelled him? Of course, there's the story of the artist who paints replicas of U.S. currency to prove some of the same point. I started to get obsessed with how abstract and far-reaching I could make the words on the card...could they really overcome physical limitations? And why do these cards make everyone smile? I made the "Add To Your Family Card," after I realized most of the previous ones were rather masculine. A little further in the "far-reaching" direction... Another powermad one. poof! Links

Interesting Trivia?! | Matt's Notes When you’re finished reading, check out the new trivial posts: More Interesting Trivia and Even More Interesting Trivia. Mum sent me this so it has to be true – right? Here are some ‘facts’ about the 1500s: They used to use urine to tan animal skins, so families used to all pee in a pot & then once a day it was taken & sold to the tannery…….if you had to do this to survive you were “Piss Poor” But worse than that were the really poor folk who couldn’t even afford to buy a pot, they “didn’t have a pot to piss in” and were the lowest of the low. Most people got married in June because they took their yearly bath in May, and they still smelled pretty good byJune. Baths consisted of a big tub filled with hot water. Houses had thatched roofs-thick straw-piled high, with no wood underneath. There was nothing to stop things from falling into the house. The floor was dirt. (Getting quite an education, aren’t you?) Sometimes they could obtain pork, which made them feel quite special. Like this:

I Wanna Deliver A Dolphin... synthetic biology project by Ai Hasegawa This synthetic biology project by designer Ai Hasegawa imagines that a woman could gestate and give birth to a baby from another species, in this case a dolphin, before eating it (+ movie). I Wanna Deliver a Dolphin... was developed by Ai Hasegawa to tackle food shortages and satisfy maternal instincts as the human population burgeons by giving women the option to become surrogates for endangered animals hunted for food. Hasegawa proposes synthesising a placenta that could support an animal in a human womb. "This project approaches the problem of human reproduction in an age of overcrowding, overdevelopment and environmental crisis," Hasegawa said. "With potential food shortages and a population of nearly seven billion people, would a woman consider incubating and giving birth to an endangered species such as a shark, tuna or dolphin?" The designer also questions whether someone would feel differently about eating a delicacy having personally carried and nurtured it.
